Fix your gaze on the centre cross. A slowly rotating field surrounds it. With true sustained fixation, the gold dots at the edges of your vision will begin to disappear.
Motion-Induced Blindness — a peer-reviewed perceptual phenomenon (Bonneh et al., 2001). The dots never actually vanish on screen — your brain suppresses them. When the grid stops, the screen may briefly seem to drift — that's the Motion Aftereffect. Both are your brain constructing, not recording, reality.
How It Works
1
Fix your gaze on the pulsing centre cross. Do not let your eyes move.
2
Gold dots will begin to vanish from your peripheral vision as fixation deepens.
3
Press Space (or tap the screen) when a dot disappears. Silent — it won't interrupt your focus.
4
Progress is tracked — your focus signals will grow across sessions.
